Title: Force detection sensor and manufacture of force detection sensor
Inventor: YAGI TAKESHI
IPC: G01P15/12
Filed: 1999-07-27
Abstract: PROBLEM TO BE SOLVED: To enhance detection sensitivity of a force detection sensor, without increase in device size by patterning nitride films formed on both sides of a semiconductor substrate to form openings, etching an oxide film formed, by oxidizing the semiconductor substrate by an etching means to form a recess in the semiconductor substrate which recess functions as a flexible portion. SOLUTION: When acceleration or pressure is applied to a force detection sensor, the acceleration or pressure is exerted on a working portion 101 and the relative position between the working portion 101, and a fixed portion 104 is changed, which causes a diaphragm 102 to bend and deform. As a result, a piezo-resistance elements 105 to 116 formed in the diaphragm 102 are also deformed. Consequently, the acceleration or pressure can be detected by measuring the electrical resistance of the piezo-elements. To form the diaphragm 102, an oxide film can be etched to form a recess in a Si substrate with the thickness of the entire workpiece kept uniform. Therefore, the thickness of the diaphragm 102 can be reduced, and the detection sensitivity can be enhanced.

Title: Optical computer
Inventor: YOSHIMURA TETSUZO
IPC: G06E3/00
Filed: 1992-08-07
Abstract: PURPOSE:To apply the optical computer to complicated optical inter-connection which is rich in flexibility by setting boards, mounted with plural spatial optical modulators, opposite each other and interchanging light alternately between the boards. CONSTITUTION:An LE or LD array, a memory, the spatial optical modulators SLM combined with an LSI such as a CPU, a holographic optical element HOE or dynamic HOE, and an optical detecting element array such as a PD are mounted on the boards. In this case, light is emitted by the LD array and irradiates the memory from the HOE, thereby reading data out. This read light is transferred by the HOE to the CPU. A pattern corresponding to the kind of arithmetic are formed in the SLM of the CPU and the composition result of the pattern and a transferred light pattern is processed. The result is transferred to the PD array through the HOE and photoelectrically converted.

Title: Press notch dwtt testing method
Inventor: AKIYAMA TOSHIYA
IPC: G01N3/00
Filed: 1986-09-10
Abstract: PURPOSE:To accurately test brittle fracture propagation stop characteristics by an easy method that tests a test-piece which is compressed and deformed to 25-40% in the plate thickness direction at the press notch part of the test- piece. CONSTITUTION:The test-piece which is compressed and deformed to 25-40% in the plate thickness direction its press notch part is prepared and used to take the test. For the purpose one edge of the intermediate of the test-piece 1 is compressed on both front and rear surfaces with press punches 2 and 2 to deform in the plate thickness directions, and a V press notch is formed with a tool 4 at the press notch parts where compressive deformation parts 3 are formed. Thus, the compressive deformation is caused at the press notch parts in the plate thickness direction to suppress fracture generating energy.

Title: Extremely thin copper adhering sheet for forming fine pattern
Inventor: URABE HIROYUKI
IPC: H05K3/38
Filed: 1997-08-06
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of break in a pattern by setting the particle size of copper obtained by an electrolytic method to a particular value, setting substantial thickness of copper foil to a particular value, and continuously adhering a sheet reinforced with reinforcing materials, as required, to a mat surface of copper foil having a particular length of a foot of the copper mat surface. SOLUTION: Copper foil is formed through an electrolytic method by controlling the rate of precipitation, so as to make the particle size less than 1 μm. Substantial thickness of copper foil according to weight method is 3 to 9 μm, but 5 to 7 μm is more preferable. If the thickness is too small, wrinkles occur more often during adhering, and the preparation of fine patterns becomes more difficult. The length of a foot of the copper foil to be used on the mat surface is less than or equal to 5 μm. If the foot length is too large, the leg portion remains without being removed by etching, when preparing fine pattern. If the length of the foot is too small, then adhesive force is too small resulting in the generation of defectives. On the mat surface of the copper foil, a base material reinforcing resin is used, as required, for continuous adhering with a heated roll.

Title: Method for writing secrecy program and device therefor
Inventor: AZUMA HIROYUKI
IPC: G06F21/60
Filed: 1996-07-23
Abstract: PROBLEM TO BE SOLVED: To evade a fear that a security program written in an ROM is analyzed by an outsider by writing only the security program in a transferred execution file in a volatile memory on an in-circuit emulator. SOLUTION: A debugger 1 transfers only a security program of an execution file for a debugger to an in-circuit emulator 2. The emulator 2 writes the transferred security program in an RAM 2b. Thus, a processing program on a debugger 1 can be executed by referring to the security program in an RAM 2b on the in-circuit emulator 2 so that the operation of the processing program on an IC card can be emulated by the debugger 1. Thus, an outsider can not analyze which place in the execution file the security program is present in.

Title: Low pressure mercury discharge tube for sterilization
Inventor: KUROSAKI TOSHIHIKO
IPC: H01J61/46
Filed: 1989-08-21
Abstract: PURPOSE:To decrease the amount of mercury oxide which adhered to the inner wall of a bulb of a discharge tube and suppress mercury discharge output from lowering by applying super fine particles of an oxide to the inner wall of the bulb of the discharge tube in the way of not preventing transmission of ultraviolet ray. CONSTITUTION:A solution containing 1-3% of metal oxide with <=100mum of average grain size is applied to an inner wall of a glass bulb 1 of a discharge tube. For example, an aqueous solution of alumina sol (aluminum oxide) with 20mum of average grain size is poured into a mercury discharge tube made of a 254nm wavelength ultraviolet-transmissible soft glass tube 1 and thereinto a mercury drop is sealed so as to coat the inner wall of the tube except the sealing part with the alumina sol, and then the inner wall is dried. Binding of an impurity present in the glass bulb surface and mercury ion or mercury compound is prevented by the super fine particles of the oxide. Also, owing to the super fine oxide particles, the surface area to absorb mercury compound is increased and thus output lowering by lighting is suppressed and desired ultraviolet radiation is achieved.

SOLUTION: A wiring 13 has a stacked structure, which includes a high fusing point metal layer 14 and an aluminum alloy layer 15 stacked thereon, and in which a compound layer 17 is produced between both these layers. To deter a compound layer 17 produced between the high fusing point metallic layer 14 and the aluminum alloy layer 15 from extending in the direction of elongation of the wiring 13, the high fusing point metal layer 14 is divided in the direction of the elongation of the wiring 13, and a dimension y1 of the interval between these divided high fusing point metal layer sections 14a is set to a value larger than twice the dimension t1 of the thickness of the compound layer 17. This can prevent the compound layers 17 growing between the opposite faces of the high-fusing point metallic sections 14a from continuing to each other.
